Although Instagram and Snapchat certainly seem to be the “in” social networks these days, particularly among young people, Facebook remains by far the most commonly used at work. Eighty-eight percent of those who check social media on the job say they visit Facebook. Twenty-one percent report using Snapchat and the same percentage say they used Twitter.

Just over a quarter of respondents report procrastinating by playing Pokémon Go, a game that was all the rage for a week or two after it was unveiled in July but has since practically disappeared from the public consciousness.

A slight majority of millennials surveyed say their company has some kind of policy regarding the use of social media on the job. But 45 percent either say there was no policy or they aren’t aware of one.

“When evaluating social media usage at work, the financial impact is astonishing,” says Tisha Danehl, vice president at Ajilon. “Social media is here to stay and mobile platforms are only getting smarter, so employers must establish clear policies in order to keep employees productive and engaged at the office.”

Danehl’s comments certainly represents the traditional philosophy on workplace management, in which employers impose strict rules on supposed “time theft.” However, many companies, particularly in the tech economy, have eschewed such restrictions out of the belief that allowing employees the discretion to take breaks from work will make them happier and more productive.
